Microbe with bizarrely tiny genome may be evolving into a virus With DNA focused almost entirely on replication, newly discovered organism blurs the line between cells and viruses

The newly discovered microbe provisionally known as Sukunaarchaeum isn’t a virus.

But like viruses, it seemingly has one purpose: to make more of itself. scim.ag/4e6y0W2

The Catch in Catching Cancer Early New blood tests promise to detect malignancies before they’ve spread. But proving that these tests actually improve outcomes remains a stubborn challenge.

Atul Butte died yesterday.
The world lost a giant.
A big bear of a man.
With a huge smile.
With love for everyone.
With energy that could power a room.
I loved everything about Atul.
I loved how he was always happy.
I loved how excited he was about science and helping people.

Open Source Genetic Database Shuts Down to Protect Users From 'Authoritarian Governments' "The risk/benefit calculus of providing free & open access to individual genetic data in 2025 is very different compared to 14 years ago."

The open-source genetic database OpenSNP is shutting down and deleting all user data after 14 years due to the risk posed by Trump administration, law enforcement abuse, authoritarian governments, and 23andMe bankruptcy:

If you think this work is cool, do note that it was done by graduate students, PDs and staff in academic labs funded by federal tax payer dollars. Which means if no federal funding, a lot less of this kind of research. Use your voice to protect federally funded research which is under attack.

Beyond genetics: driving cancer with the tumour microenvironment behind the wheel - Nature Reviews Cancer In their Review article, Fuchs and colleagues discuss how a single or a few mutations in adult cells can lead to invasive cancers without a high mutational burden, demonstrating that non-genetic factors induce the epigenetic changes necessary for tumorigenesis.
